There is an unchecked dereference of "input->fe" in the call to tuner_attach_tda18271() and there is a second unchecked dereference a couple lines later when we do: input->fe2->tuner_priv = input->fe->tuner_priv; But actually "intput->fe" can't be NULL because if demod_attach_drxk() fails to allocate it, then we would have return an error code.
